German authorities arrested five men Tuesday on allegations they aided the Islamic State group in Germany by recruiting members and providing financial and logistical help.

The federal prosecutor's office said in a statement that the men were arrested on suspicion of supporting a terrorist organization. The arrests were made in a series of raids in the western state of North Rhine-Westphalia and the northern state of Lower Saxony.

The prosecutor's office, which handles all terrorism cases, said the suspects weren't known to have links to IS suspect Jaber Albakr, who killed himself in prison in October two days after being arrested on suspicion of plotting to attack a Berlin airport with homemade explosives.

The five men are suspected of recruiting young Muslims in Germany, and raising funds to send them to Syria to join IS, prosecutors said. They're also accused of providing logistical support for the trips.

One of the suspects, a 32-year-old Iraqi citizen identified as Ahmad Abdulaziz Abdullah A., who also goes by the alias of Abu Walaa, is accused of being the ringleader of the group. He openly supported the IS group, attended several extremist events as a speaker and approved the departure of those willing to go to Syria, prosecutors said.
